Structural and electronic properties of single zinc etioporphyrin molecules adsorbed on Al 2 O 3 /NiAl(110) were probed by a low‐temperature scanning tunneling microscope (STM). Scanning tunneling spectroscopy (STS) revealed progressions of spectral features corresponding to the vibronic states of individual molecules that depend strongly on the molecular conformations. Vibronic features observed by STS were compared with the results from fluorescence induced by tunneling electrons (tunneling‐induced fluorescence, TIF).
